Engine/Transmission (1994 - 1998) 47re/exhaust brake question

[Bromiley99]

97 dodge auto. I was reading through TDR issue 64 which covered adding a brake to our trucks equipped with the 47re, in the article they installed a product made by BD called a "pressureloc." The purpose of the device is to raise line pressure while your not hitting the throttle (using exhaust brake) keeping your converter from slipping. The device is kinda expensive does anyone know of another company that makes a similar product that's better or preferably cheaper? I've looked at not had much luck, thanks!!
